Year 7
Prior learning/place of lesson in scheme of work
Learn how to return the modulus, math->mod to determine if you will plot image. We will be learning how to return the modulus by using a local variable, input on shake, if (conditional), modulo, as well as simple commands such as plot image.
What the teacher needs to know / QuickStart Computing Glossary
- Algorithm: An unambiguous set of rules or a precise step-bystep guide to solve a problem or achieve a particular objective.
- Input: Data provided to a computer system, such as via a keyboard, mouse, microphone, camera or physical sensors.
- Output: The information produced by a computer system for its user, typically on a screen, through speakers or on a printer, but possibly through the control of motors in physical systems.
- Programmable toys: Robots designed for children to use, accepting input, storing short sequences of simple instructions and moving according to this stored program.
- Program: A stored set of instructions encoded in a language understood by the computer that does some form of computation, processing input and/or stored data to generate output.
- Repetition: Executing a section of computer code a number of times as part of the program.
- Simulation: Using a computer to model the state and behaviour of real-world (or imaginary) systems, including physical or social systems; an integral part of most computer games.
- Variables: A way in which computer programs can store, retrieve or change data, such as a score, the time left, or the user’s name.

Objectives
- learn how to create a local variable as a place where you can store data, so that you can use it in your code, across functions, and in nested code blocks
- learn how to run code when the micro:bit is shaken; when running code in the browser, moving the mouse quickly simulates shaking
- learn how to conditionally run code depending on whether a condition is true or not
- learn how to return the modulus
- learn how to display an image on the BBC micro:bit's LED screen

Progression Pathways / Computational Thinking Framework
Algorithms
- Designs solutions (algorithms) that use repetition and two-way selection, ie if, then and else.(AL)
- Uses diagrams to express solutions.(AB)
- Uses logical reasoning to predict outputs, showing an awareness of inputs (AL)
- Shows an awareness of tasks best completed by humans or computers (EV)
- Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB)
- Recognises that different solutions exist for the same problem (AL) (AB) Understands that iteration is the repetition of a process such as a loop (AL)
- Recognises that different algorithms exist for the same problem (AL) (GE)
- Represents solutions using a structured notation (AL) (AB)
- Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE)
Programming & Development
- Creates programs that implement algorithms to achieve given goals (AL)
- Declares and assigns variables(AB)
- Uses post-tested loop e.g.‘until’,and a sequence of selection statements in programs,including an if,then and else statement(AL)
- Understands the difference between, and appropriately uses if and if, then and else statements(AL)
- Uses a variable and relational operators within a loop to govern termination (AL) (GE)
- Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL)
- Selects the appropriate data types(AL) (AB
Data & Data Representation
- Understands the difference between data and information(AB)
- Uses filters or can perform single criteria searches for information.(AL)
- Performs more complex searches for information e.g. using Boolean and relational operators(AL) (GE) (EV)
- Defines data types: real numbers and Boolean (AB)
Hardware & Processing
- Knows that computers collect data from various input devices, including sensors and application software (AB)
Information Technology
- Collects, organizes, and presents data and information in digital content (AB)
- Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution (EV)
- Uses criteria to evaluate the quality of solutions, can identify improvements making some refinements to the solution, and future solutions (EV)
- Recognises ethical issues surrounding the application of information technology beyond school.
Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
